Yes, completely. Synthetic oil is very durable so changing at least the filter will help keep it cleaner until the recommended 15K mile oil change. If you follow just the recommended oil change at 15k, I don't see how changing the filter could be any worse.

well i guess i see your point. I know Synthetic oil is durable but 15k is just way too much.. and thats coming from all the mechanics i know. My dad was a mechanic for 25 years and i sure dont follow the recommended oil change at 15k. Since day one i have been doing my oil change takes 30 minutes and cost 130 every 15k half is dealer and half i pay and DIY.

If you are thinking of keeping the car i highly suggest to change both...

I change my oil every 5K miles, and I always use BMW oil & filter, for $80 you'll get a filter and 7 qts of oil. Let me tell you something, my oil is almost pitch black @ 5K miles. I don't care what BMW tells you, 15K miles between oil changes is another way to deposit dirty particles inside your engine, not healthy for the long run. BMW also says their differential & tranny fluids, and coolant are "Lifetime". Any REAL mechanic will laugh at that fact. It's your call pal..!! Or you can also do 7.5K like a lot of folks here!! But don't waste your time and money on just changing the filter.
